Here's the dilemma. I just sand blasted and powder blasted my entire 1980 CJ. Now I need to put some paint on it after I repair a couple wholes in the body and frame work. What is the best thing or who has had what kind of experience with each of these products; POR15, Chassis saver, or Rust Bullet? I am looking to make body and frame repairs then spray bottom asap to prevent any more rust from comming back. Anything else you could recommend would be great as well to keep preventing rust in the future. thank you.

I used chassis saver on the front and back parts of my frame as well as under my tub and skid plate. I love it so far. Its easy to put on, just sand down the really rough stough and it goes right over anything else. Seems to be lasting too. I also found some stuff from eastwood that would help the inside of the frame. Not sure how easy it would be to do or if its even worth it but seems interesting.

Self ecthing bare metal primer, epoxy is best. But the metal should be preped with a metal conditioner first. I have used a Dupont product its an acid/alcohol/ you mist it on the metal turned a bluish color. Then hit it with etching primer. It could sit from there with out rusting. Bare metal will start to rust the secound it hits the air.
